ABSTRACT:
An airborne toner collection manifold for an electrostatographic printer for coupling in fluid flow communication with a vacuum source includes an inlet, a collection duct, a first exhaust duct and a second exhaust duct. The inlet defines a gap slot extending longitudinally between a first end and a second end. The collection duct is adjacent to the inlet and has a first end extending longitudinally at least to the first end of the gap slot of the inlet and a second end extending longitudinally at least to the second end of the gap slot of the inlet. The collection duct defines a cavity in fluid flow communication with the gap slot. The first exhaust duct is in fluid flow communication with the cavity of the collection duct and is configured to be coupled for fluid flow communication with the vacuum source. The second exhaust duct is in fluid flow communication with the cavity of the collection duct and is configured to be coupled for fluid flow communication with the vacuum source. The second exhaust duct is displaced from the first exhaust duct and is positioned relative to the first exhaust duct to be closer to the second end of the collection duct.
